All your purchases are tied to your account. Since you have purchased the music, you should be able to will it to someone else just like you would if you had purchased the phyiscal CDs. Does Apple's account system and terms of service allow this? If you die without telling anyone else your password, will Apple assist you in unlocking the files?
Not that I'm expecting to die but this just occured to me.
